[0031] like Figure 1-5 As shown, the present invention proposes a compound fertilizer rotary drum granulator, comprising a base 1, a set of mounting blocks 2 fixedly connected to the base 1, a rotating plate 3 rotatably connected to the inner side of the mounting block 2, and a support plate 4 fixedly connected to the base 1;

[0032] A group of cylinders 6 are provided on the base 1 , and a driving member 5 for driving the cylinders 6 is provided on the base 1 .

[0033] In the present invention, the driving member 5 located on the cylinder 6 and the base 1 can continuously roll the material put into the cylinder 6, and can also push the cylinder 6 to lift and separate, so as to improve the fertilizer granulation effect and efficiency, and improve the cleaning convenience.

[0034] In an optional embodiment, the driving member 5 includes a movable plate 51 slidably connected to the base 1, and the outer side of the right cylinder 6 is rotatably connected to a support ring 56. The inner sides of the rotating plate 3, the support ring 56, the support plate 4 and the movable plate 51 are all rotatably connected to a guide wheel 52. The outer sides of the two cylinders 6 are fixedly connected to two guide rings 57 that are slidably connected to the guide wheel 52. A groove 54 is provided on the upper surface of the base 1, and the inner side of the groove 54 is hinged to a hydraulic rod 55 whose end is hinged to the lower end of the support ring 56. A rectangular block 58 is fixedly connected to the inner side of the movable plate 51, and a support block 59 is fixedly connected to the rectangular block 58. The support block 59 is threadedly connected to a threaded rod 510 whose end extends to the inside of the middle right guide ring 57.

[0035] It should be noted that the inner walls of the two cylinders 6 are concave, so that the material put into the cylinder 6 can continue to roll into balls in the cylinder 6;

[0036] The other end of the right cylinder 6 is fixedly connected to a docking ring 9, one end of which extends to the inside of the left cylinder 6. A docking block 10 is fixedly connected to the outside of the docking ring 9. One end of the left cylinder 6 is provided with a docking groove located on the outside of the docking ring 9. The specifications of the docking groove are compatible with the specifications of the docking ring 9 and the docking block 10. Through the cooperation of the docking ring 9 and the docking block 10, the rotating left cylinder 6 can drive the right cylinder 6 to rotate synchronously, and improve the sealing of the two cylinders 6 after docking.

[0037] In this embodiment, since the inner walls of the two cylinders 6 are concave, the input materials can be accumulated in the cylinder 6 and continue to roll into balls along with the cylinder 6. After the hydraulic rod 55 is activated and pushes the two fitted cylinders 6 into an inclined shape, the granular fertilizer after balling can be conveniently discharged to improve the fertilizer balling effect and balling efficiency. By rotating the threaded rod 510 to extend into the left guide ring 57 on the right cylinder 6, the support ring 56 can be pulled by the hydraulic rod 55 to separate the two cylinders 6, thereby improving the convenience of cleaning.

[0038] Among them, the lower end of the movable plate 51 is convex-shaped, and its convex end is slidably connected in the groove 54. The inner side of the groove 54 is fixedly connected to a cross bar 53 with one end passing through the convex end of the movable plate 51.

[0039] Among them, a threaded hole located on the outside of the threaded rod 510 is opened in the middle of the support block 59, and the threaded hole cooperates with the thread on the outside of the threaded rod 510. The left guide ring 57 on the right cylinder 6 is opened with a plurality of support grooves, and the plurality of support grooves are distributed in a circular shape and at equal intervals, and the specifications of the support grooves are adapted to the specifications of the threaded rod 510. The left guide ring 57 on the right cylinder 6 is supported and limited by the threaded rod 510 extending into the support groove, so as to improve the stability of the hydraulic rod 55 when driving the right cylinder 6 to move along a parallel horizontal plane.

[0040] In an optional embodiment, a processing part 7 for processing fertilizer is provided on the right cylinder 6; the processing part 7 includes a support frame 71 fixedly connected to the outside of the support ring 56, and a rotating motor 72 is fixedly installed on the outside of the support frame 71. The output shaft of the rotating motor 72 is fixedly connected to a rotating rod 75 with one end passing through and extending to the inside of the cylinder 6, and a plurality of stirring rods 77 are fixedly connected to the outside of the rotating rod 75. A material guide tube 76 with one end extending to the inside of the cylinder 6 is fixedly connected to the support frame 71, and a support cover 74 located on the outside of the rotating rod 75 is fixedly connected to the inside of the support frame 71.

[0041] In this embodiment, the material put into the cylinder 6 can be stirred by a plurality of stirring rods 77 extending into the cylinder 6. At the same time, when steam or water is transported to the cylinder 6 through the connecting pipe 73, it can be discharged through a plurality of discharge holes 78 on the plurality of stirring rods 77 to improve the uniformity of the material when in contact with water or steam, thereby further improving the ball forming efficiency.

[0042] It should be noted that the interiors of the rotating rod 75 and the plurality of stirring rods 77 are hollow, and the hollows of the rotating rod 75 and the stirring rods 77 are connected to each other. The rotating rod 75 is provided with a plurality of guide holes located on the inner side of the support cover 74. The outer side of the support cover 74 is connected to the connecting pipe 73. The stirring rod 77 is provided with a plurality of discharge holes 78, so that the water or steam transported by the connecting pipe 73 can be transported to the stirring rod 77 through the rotating rod 75 and then discharged through the discharge holes 78.

[0043] The feed end of the connecting pipe 73 is in communication with the output end of water or steam, and is used to transport water or steam into the support cover 74 .

[0044] In an optional embodiment, a rotating member 8 for driving the cylinder 6 to rotate is provided on the rotating plate 3, and the rotating member 8 includes a rack 81 fixedly connected to the outer side of the other end of the left cylinder 6. A driving motor 82 is fixedly installed on one side of the rotating plate 3, and the output shaft of the driving motor 82 is fixedly connected to a gear 83 whose one end is meshed with the rack 81.

[0045] In this embodiment, the started driving motor 82 can drive the left cylinder 6 to rotate through the meshing gear 83 and the rack 81.

[0046] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., as well as the existing disclosed power connection technology, which will not be described in detail in this article.

[0047] The working principle in the above embodiment is:

[0048] The started driving motor 82 can drive the left cylinder 6 to rotate through the meshing gear 83 and the rack 81. After the rotating left cylinder 6 rotates synchronously with the right cylinder 6 through the docking block 10 on the docking ring 9, the fertilizer material that needs to be pelletized can be added through the guide pipe 76. During the feeding process, the rotating motor 72 is started to drive the rotating rod 75 and the stirring rod 77 to rotate slowly and uniformly. At the same time, since the rotating rod 75 and the stirring rod 77 are connected to each other, after water or steam is transported through the connecting pipe 73, the water or steam can enter the support cover 74, and then enter the rotating rod 75 through the guide hole on the rotating rod 75, and finally flow into the stirring rod 77, and can be discharged through the discharge hole 78, so as to improve the uniformity of the material when it contacts the water or steam.

[0049] After the fertilizer material is pelletized, the hydraulic rod 55 can be started to push the support ring 56 to drive the cylinder 6 to rotate along the mounting block 2 to an inclined state, and the pelletized fertilizer particles can be discharged. When the cylinder 6 needs to be lowered to clean the inner wall of the cylinder 6, the threaded rod 510 can be rotated to extend to the left guide ring 57 on the right cylinder 6. After supporting and limiting the guide ring 57, the support ring 56 can be pulled by the hydraulic rod 55 to drive the right cylinder 6 to move toward the side away from the left cylinder 6 for separation, thereby facilitating the operator to clean the inner wall of the cylinder 6.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
